Product details
Overview
M30162040108X0IWAY from Renesas is a 16Mbit serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR operation, 1.71–2.0V supply, and industrial temperature range (−40°C to +85°C) in 8-pad DFN (WSON) package. It delivers SRAM-compatible read/write timing, zero write latency, and persistent data retention without backup power - ideal for real-time data logging in factory automation controllers.
For engineers reviewing the M30162040108X0IWAY datasheet, M30162040108X0IWAY pinout, M30162040108X0IWAY application, or M30162040108X0IWAY equivalent, key selection criteria include its 108MHz SDR QSPI speed, hardware/software write protection (WP# pin + configuration registers), 256-byte augmented storage array, JEDEC reset support, and industrial-grade thermal performance.
Technical Context
The M30162040108X0IWAY implements a 40nm pMTJ spin-transfer torque MRAM array with true random-access capability, supporting both Single Data Rate (SDR) and Double Data Rate (DDR) QSPI modes - though this specific variant is rated for 108MHz SDR only. Its architecture includes dedicated command/address/data paths per SPI mode (e.g., 1-4-4 for Quad I/O), eXecute-In-Place (XIP) functionality, and dual power states (Deep Power Down, Hibernate) with full data retention.
It integrates hardware-based write protection via the WP# pin and software-based protection through configurable status and block protect bits (BPSEL[2:0]), plus independent 256-byte augmented storage with per-section write lock. All register access (Status, Configuration, Unique ID, Serial Number) occurs over the same QSPI bus using dedicated address-mapped register space distinct from main memory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Mbit (2 MByte) main memory array with linear 24-bit addressing (000000h–1FFFFFh) |
| Interface | QSPI (4-4-4 mode), 108 MHz SDR clock rate - enables sub-100 ns random read access with no erase cycles |
| Supply Voltage | 1.71 V – 2.00 V - compatible with modern low-voltage microcontroller I/O domains and reduces system power |
| Operating Temperature | −40°C to +85°C (Industrial grade) - validated for continuous operation in uncontrolled factory environments |
| Endurance & Retention | Virtually unlimited write cycles (>10¹⁵) and ≥20-year data retention at 85°C - eliminates wear leveling firmware overhead |
| Package | 8-pad DFN (WSON), 5.0 mm × 6.0 mm - surface-mount compatible with standard reflow profiles and high-density PCB layouts |
| Data Protection | Hardware WP# pin + software-configurable top/bottom/block protection (BPSEL[2:0]) - prevents accidental writes during firmware updates |
Pinout & Package
8-pad DFN (WSON) package, 5.0 mm × 6.0 mm, moisture sensitivity level (MSL) 3, lead-free and RoHS/REACH compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable signal; device enters standby when high, and requires falling edge before instruction start |
| WP# / IO[2] | Bidirectional I/O / Write Protect | In SDR mode: hardware write protect for status register when pulled low; in QPI mode: bidirectional data line IO[2] |
| SI / IO[0] | Input / Bidirectional Data 0 | In SDR: serial input only; in QPI: bidirectional data line IO[0] - supports command/address/data transfer |
| CLK | Clock Input | Synchronous timing reference; latches command/address on rising edge, outputs data on falling edge (SDR) |
| IO[3] | Bidirectional Data 3 | QPI mode only - completes 4-line data path for high-speed quad read/write operations |
| SO / IO[1] | Output / Bidirectional Data 1 | In SDR: serial output only; in QPI: bidirectional data line IO[1] - complements IO[0], IO[2], IO[3] |
| VCC | Power Supply | 1.71–2.00 V core and I/O supply - decoupling capacitor required adjacent to pin per datasheet layout guidance |
| VSS | Ground | Common reference for core and I/O circuits - must be low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| STT-MRAM Technology | 40 nm pMTJ cell structure enabling zero write latency, no write endurance limit, and instant non-volatility without capacitors or batteries |
| eXecute-In-Place (XIP) | Enables continuous sequential reads/writes without repeated command overhead - reduces effective access time by up to 40% vs standard SPI flash |
| Augmented Storage Array | 256-byte user-programmable section, divided into eight 32-byte lockable blocks - ideal for storing calibration data or firmware signatures |
| JEDEC Reset Support | Standardized reset command (66h) restores device to known state without power cycle - critical for field-upgrade reliability |
| Low-Power States | Deep Power Down (IDPD) and Hibernate modes draw <1 µA while preserving all memory contents and register configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress Semiconductors FM25V10-G | 1 Mbit F-RAM, 40 MHz SPI, 2.0–3.6 V supply - lower density, slower interface, wider voltage range | Limited to smaller config stores; lacks QPI, XIP, or augmented storage - suitable only for basic parameter retention | Select when cost sensitivity outweighs performance needs and density <4 Mbit suffices |
| Infineon Technologies CY14B108N-ZSP25XI | 8 Mbit nvSRAM, 25 MHz parallel interface, 3.0–3.6 V - higher latency, parallel bus, no QSPI support | Requires PCB redesign for 32-pin SOIC footprint and parallel bus routing - incompatible with existing SPI host designs | Choose only for legacy parallel-interface systems where pin count and board space permit |
Compared with FM25V10-G and CY14B108N-ZSP25XI, the M30162040108X0IWAY provides 2× higher density than the F-RAM, 4.3× faster interface than the nvSRAM, and native QSPI/XIP support - making it the sole option for high-throughput, space-constrained, and firmware-upgradable industrial systems.

FAQ
What is the operating voltage range for the M30162040108X0IWAY?
The M30162040108X0IWAY operates from 1.71 V to 2.00 V. This narrow 1.8 V nominal range ensures compatibility with modern low-power microcontrollers and reduces system-level power consumption. Operation outside this window is not guaranteed, and the device will not function below 1.71 V or above 2.00 V per datasheet specifications.
Does the M30162040108X0IWAY support Quad SPI (QPI) mode?
Yes, the M30162040108X0IWAY supports Quad SPI (QPI) mode with 4-4-4 command-address-data configuration. It achieves 108 MHz operation in Single Data Rate (SDR) QPI, delivering up to 54 MB/s effective throughput - significantly faster than standard SPI flash and enabling efficient XIP execution directly from memory.
How does write protection work on the M30162040108X0IWAY?
The M30162040108X0IWAY implements dual-layer write protection: hardware-based via the WP# pin (active-low, disables status register writes when enabled), and software-based via BPSEL[2:0] bits in the status register (configurable top/bottom/block locking). Both mechanisms can be used independently or concurrently to safeguard memory regions during firmware updates or field operation.
What is the purpose of the Augmented Storage Array in the M30162040108X0IWAY?
The M30162040108X0IWAY includes a dedicated 256-byte Augmented Storage Array, segmented into eight 32-byte programmable sections. Each section can be individually write-protected - making it ideal for storing calibration coefficients, security keys, or firmware version stamps that require high integrity but infrequent updates, separate from main memory wear cycles.
Is the M30162040108X0IWAY pin-compatible with other members of the Mxxxx204 family?
Yes, the M30162040108X0IWAY shares identical 8-pad DFN (WSON) pinout and electrical interface with all Mxxxx204 variants, including M1004204, M3008204, and M1016204. Pin functions (CS#, CLK, IO[0–3], VCC, VSS, WP#) are fully consistent across densities and speed grades - enabling drop-in replacement within the same package and temperature grade.
